The system consists of a compact, simple-to-operate console, an easily transportable, no-winch tow fish, and all accessory equipment, such as Kevlar-reinforced cable, tow bar, ballast, and lead weight. Add any super-VGA color monitor and you have a side scan system that can search and map the seabed in stunning detail. Such objects as archaeological sites, downed planes, and shipwrecks are displayed with superb color (or black and white, if you wish) discrimination and screen resolution. Plus, you have the choice of either a medium frequency (107 kHz) model for long range with good resolution, or a high-frequency (300 kHz) for | | Richest American Treasure Found With A WESMAR Side Scan Sonar When the SS Brother Jonathan, a wooden-hulled paddle steamer, sank off the coast of Crescent City, CA in 1865, it was carrying among it's precious cargo 250 passengers and 1,207 gold coins. After three years of searching, using other side scan systems and sophisticated measuring devices, it took the WESMAR Side Scan Sonar only 11.5 minutes to resolve the question of where the wreck resided. "The WESMAR image was so clear we could see the stern, the paddle hubs and could even see the damage from the sinking," said James Wadsley, principal in Deep Sea Research LLC. "WESMAR's Side Scan Sonar is lightweight and inexpensive in comparison to some of the equipment we tried... it can't be beat." | | |

By using the onscreen menu, you can select from two black and white combinations, two full-color combinations, and 12 two-color combinations. WESMAR engineers have provided a unique color threshold design that adapts for differing search conditions. What these color combinations allow you to do is "unmask" bottom targets hidden by extraneous soundbeam reverberation. You can specify among linear, logarithmic, or exponential color separations, which can reduce or eliminate unwanted display clutter, while enhancing desired | | |
